High Vibration of a Centrifugal Compressor Casing Caused by the Gas Leakage across a Damaged Gasket
Abstract
A sudden increase of casing vibration along with loud noise and shaking of casing and process piping were observed on a large sales gas centrifugal compressor, while the rotor vibration was below alarm level. When the unit was shut down and restarted several times, the issue occurred again after few hours of operation. A detailed investigation of site data combined with aerodynamic analysis (CFD) and mechanical analysis (FEA) allowed identification of the unexpected root cause of this severe casing vibration issue as the rupture of an elastomer gasket inside the compressor casing.
